Gross started as an apprentice glazier at a stained glass school, where he learned to think in color. In 1988 he obtained his master’s degree in this field and subsequently completed the painting course in Saarbrücken cum laude. Like most people, Gross grew up with plastic, an industrially produced wonder material. So for him it is the most honest material, because it seems so familiar.
Everything is possible with it, but at first it seems distant to an artist and only intended for industrial applications. He has made this material his own and made it useful for his ideas. He has developed a painting and making craft around plastic. He has devised techniques that are reminiscent of techniques from glass processing. In it he combines the plastic with valuable pigment and oil paint. It is image carrier and paint in one. In his work Gross shows in a colorful way the decline of a society based on growth.
